Stability of the structure of emulsion formed by oil drops suspended in an alcohol-water solution of an identical density under the action of a local heat pulse is experimentally studied. Stability of the emulsion structure characterized by the distribution of the numerical concentration of drops over the medium volume is considered within a time period where the interaction (mutual attraction) of drops with a given initial volume concentration may be neglected. As a result, a condition was determined according to which the emulsion structure is stable if the product of the amount of heat brought to the medium by the local heat pulse and the heat-pulse duration does not exceed some value, which is constant for a given liquid.
